Identifying and Addressing Corn Stand Count Discrepancies in Variable Soil Conditions
20 May 241m 53s

Matt and his team are conducting stand counts on corn fields to determine plant population per acre. Using three ropes, each 13.9 feet long, they measure populations in various field spots and calculate averages. Results indicate that lower populations correlate with areas having the lowest CEC (cation exchange capacity), particularly in deep sand regions. Additionally, discrepancies in corn growth stages from V1 to a spike are noted.

00:00 We're out here today doing stand counts on some more skimpy corn. We got three ropes that are 13 nine feet, 00:07 which will tell us our population per acre. Each person's getting a population count, and then we will add those up, divide that by three. 00:15 We do this in multiple spots of the field to two. Make sure we got the right counts. What'd you get, Gina? 33. 33. 46. 26. 25. 00:28 25. So we'll add those three together and we'll have a stand count for this spot. What we figured out, number one is all our skimpy corn is 00:37 where our lowest CECs are. So in our deep sand spots like we're standing in now, lower the CEC, 00:42 the less population we got some places we got decent population, but the growth stage is gonna be somewhere between V one to a spike. 00:50 So that's gonna hurt you too. But one thing I noticed here, and I hope you can see it on camera, 00:54 and I kind of drew it out here. You know, we try to do this twin row and there's a skimpy row here and a good row here. 01:00 The difference is everywhere you see the skimpy row, there's what I call water pockets. 01:04 So there's places in here, even though we're on a flat bed, that that seed trench was a little bit lower closing wheel, 01:10 done something a little bit different or the bed height was different. When the planter come through, those are your weak spots. 01:16 So if you look down the twin row, everywhere you see a dark spot in the dirt is where the corn set in water. 01:21 Maybe an hour longer, maybe two hours longer. We say we get higher yields outta twin row. This right here will equal the same 01:27 as a single row, this bed. Then you walk over here, this bed done perfect. This will be 10 bushels better than single row in the delta 01:35 because the bed was flatter and the corn planter planted more even. So there's 10 bushel difference in this and this just 01:41 because of the water pockets in the one row that I'm not sure what to do about thought for the day. Alright, so.
